function heartrate = importfile_HR(filename, startRow, endRow)
%IMPORTFILE Import numeric data from a text file as column vectors.
%   HEARTRATE = IMPORTFILE(FILENAME) Reads data from text file FILENAME for
%   the default selection.
%
%   HEARTRATE = IMPORTFILE(FILENAME, STARTROW, ENDROW) Reads data from rows
%   STARTROW through ENDROW of text file FILENAME.
%
% Example:
%   heartrate = importfile('B_30Oct2015-144315_pwa.txt',2, 2);

%% Post processing for unimportable data.

% script.
